There are 4 different types of security cameras:

• Fixed indoor cameras
• Dome cameras
• PTZ cameras
• Bullet cameras

Fixed indoor cameras are stationary cameras that come in a variety of different styles. They are popular due to their affordability and ease of use.

Dome security cameras are those dark, bulb-shaped devices you’ve probably noticed in the ceiling of a department store, a bank, or a government office. They’re designed to be tamper-proof.

PTZ cameras (pan-tilt-zoom cameras) allow you to pan side-to-side, tilt up and down, and zoom remotely. If you’ve got a wide viewing angle to cover, one PTZ camera can get a fuller picture compared to most others.

Bullet cameras are fixed cameras that can be used indoors or outdoors. This is probably the most traditional design that we associate with surveillance cameras. They’re a little bit larger than the other options, but these are most commonly found in surveillance camera kits.

We can break down all of these camera types into two categories: wireless and wired.

Both have their pros and cons:

Wireless cameras have become popular in the past decade as data transfer rates over WiFi increased, and wireless connections became more reliable. These are often used for general surveillance, baby monitors, and nanny cams.

There are also two different types of wireless cameras: traditional wireless cameras and wire-free wireless cameras.

Outdoor cameras can be used indoors but indoor cameras cannot be used outdoors as they lack the weather resistance needed to keep out dust and water. Without sufficient protection, the camera could become damaged and malfuncation.
